After updating your language.toml file. Do the following:

1. Build up on the shell

$ hx -g fetch
$ hx -g build

2. Make a queries directory and copy the query files to this directory.

$ mkdir -p $HELIX/runtime/queries/roc # make your queries directory for roc
$ cp -r $HELIX/runtime/grammars/sources/roc/queries $HELIX/runtime/queries/roc

Note $HELIX typically points to ~/.config/helix

Add the code in neovim/roc.lua to your config somewhere. Copy the folder neovim/queries to your neovim config at after/ or in a custom neovim plugin at its root directory ./ eg: after/queries/roc/highlights.luaor my_roc_plugin/queries/roc/highlights.lua

A package providing a major mode for Roc is under development.

Creating language parsers is not for the faint of heart. However, if you must, see Creating parsers to get started.

You will need:

1. The tree-sitter cli, which will be installed when you run npm install
2. A c compiler like gcc or clang

Once you've made a change, to test it, run:

tree-sitter generate
tree-sitter test 

If you add a new feature you should add a test to one of the test files in test/corpus/*.txt once you are happy with you changes run

tree-sitter test --update

and it will update the test files with your new parsed tree
